Root Canal Treatment: Root canals are done as a last resort to save the tooth once the decay has spread to the pulp or once the fracture on a tooth affects the pulp inside a tooth. In order to then save the tooth, the pulp inside the tooth is shaped and disinfected and eventually filled with a biocompatible material. This treatment blocks the spread of infection to the bone surrounding the tooth. Most root canal treated teeth should be covered with a crown so as to prevent the tooth from fracturing.

This treatment may be done in single or multiple visits depending on the level of infection and complexity of the anatomy of the tooth. Root canal treated teeth in most cases have to be restored with a crown. As the pulp (which contains nerves and blood vessels inside the tooth) has been removed from the tooth, it leaves the tooth more dehydrated and hence more susceptible to fracture.
